Given:
There are 50 U.S. states.
Seven twenty-fifths of the state share a land border with Canada or Mexico.
That means,
7[tex]\frac{20}{5}[/tex]
= 7 x 4
= 28
a number of 28 states share the border with Canada or Mexico.
Of those 2/7 share a border with Mexico,
that means, the number of,
= 28 - 28 x 2/7
= 28 - (4 x 2)
= 28 - 8

Given m||n, find the value of x and y
Answer:
x = 8
y = 29
Step-by-step explanation:
8x - 11 = 9x - 19
x - 19 = -11
x = 8
2y - 5 = 9x - 19
2y - 5 = 9(8) - 19
2y - 5 = 72 -19
2y - 5 = 53
2y = 58
y = 29

How do you find the unknown side if you have the area and the other side?
Answer:
if you have the area (i'm assuming this is a square or rectangle) and one side, you can use division to find the other side
the formula for area is (side 1)(side 2) = area
so using this, divide the area by the side you do know, and you will get the unknown side

Based on the information, determine which sides of quadrilateral ABCD must be parallel m angle A= 67°, m angle b = 120°, m angle c=73°, m angle d =100°
Answer:
None of the sides are parallel.
Step-by-step explanation:
Quadrilaterals are all figures or shapes bounded by four sides. Some common examples are: square, rectangle, trapezium, rhombus, parallelogram etc.
Two or more lines are said to be parallel, if none of the lines meet when extended till infinity. i.e they are at [tex]180^{o}[/tex] to one another.
Given a quadrilateral ABCD with the measures of angles as given, none of its sides would be parallel.

Use synthetic division to find all the factors of this polynomial
4x^3+5x^2-18x+9
Answer:
(x-1)(4x-3)(x+3)
Step-by-step explanation:
The factor of the polynomial 4x³ + 5x² – 18x + 9 will be (4x – 3), (x + 3), and (x – 1).
What is a factorization?It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.
The polynomial is given below.
⇒ 4x³ + 5x² – 18x + 9
Then the factor of the polynomial will be
⇒ 4x³ – 3x² + 8x² – 6x – 12x + 9
⇒ x²(4x – 3) + 2x(4x² – 3) – 3(4x – 3)
⇒ (4x – 3)(x² + 2x– 3)
⇒ (4x – 3)(x² + 3x – x – 3)
⇒ (4x – 3)(x + 3)(x – 1)

3n+4 first the 7 terms
Answer:
4, 7, 10, 13, 16, 19, 22
Step-by-step explanation:
Not sure if there is more to this question but here is what I assume:
We want to find the first 7 terms of this equation given 3n+4
Assuming we are starting at 0 we plug 0 in for n.
3(0) + 4 → 4
So our first answer is 4
We continue by pugging in the next numbers after that to get to the first 7 terms
3(1) + 4 → 7
3(2) + 4 → 10
3(3) + 4 → 13
3(4) + 4 → 16
3(5) + 4 → 19
3(6) + 4 → 22
